A new “Side” to Lindsay Lohan’s new project. Sam Worthington set for more epic adventure. Plus, two Hollywood leading ladies take on Marilyn Monroe! It’s all in the latest edition of the AccessHollywood.com Casting Call…

What’s the only thing better than one Marilyn Monroe? Apparently, two Marilyn Monroes… at the same time.

News out of the Cannes Film Festival is that both Naomi Watts and Michelle Williams will take on the role of the iconic blonde bombshell in separate projects.

Watts, 41, will play Monroe in the biopic “Blonde,” based on author Joyce Carol Oates’ controversial, fictionalized 2000 memoir of the same name.

Meanwhile, Williams, 29, is in talks to play Monroe in The Weinstein Company’s “My Week With Marilyn,” which centers on the icon’s time in England while filming “The Prince and The Showgirl” with Laurence Olivier in 1957, per Deadline.

According to Deadline, another Hollywood bombshell turned down the part before it went to Williams – Scarlett Johansson.

“My Week” is set to begin shooting in September, while “Blonde” will begin production in January 2011.
